AUTQMATIC yHAY SHAKER AND SEED srr'rnn.

Application filed December This invention relates to an automatic hay shaker and seed sifter for use on mowing machines.

The object of the invention is the provision of a device of this character which is actuated from the Vcutter bar or by the4 means which operates the cutter bar and which is effective to separate the seed from the hay and to displace the hay rearwardly of the dev-ice and onto the ground.

A further object is the provision of a device of the Vcharacter vspecified and having the advantages enumerated and which is adapted for attachment on practically any type of mowing machine without the necessity of modifying its construction in any way.

A. stil-l further object is thel provision of a device of this character wherein the cutter bar ofthe mowing machine may be raised without lifting backthel seed pan, the operating Vbar for the sifting screen being mount.- ed to automatically move as maybe required .when the cutter bar is raised.`

Other objects and advantages reside in cert-ain novel A'features of the construction, arrangement and combination of parte which will be hereinafter more fully describedl and particularly pointed outV in the appendedclaims, reference being had to the accompanying drawings forming a part of `this specification, and in which Figurer 1 isa plan view showing one embodiment of the invention,

Figure 2 is a view in longitudinal vertical section on the line 2-2 of Figure 1, partsbeing omitted for the sake of simplicity and illustration.

Figure 3 is a fragmentary perspective view illustrating the means for shifting the sifting screen, and

Figure l is a fragmentary detail perspective vienr of one of the connecting bars employed for fixing the sifting screen to its operating rod,

Referring to the drawings, the numeral designates a cutter bar of a mowing machine which has an arm 11 pivotally oo nnectechas at 12, with an operating element 13, the operating element reciprocatingj'rthe' A seed pan 14 is supported by brackets 15 on the cutter bar .10 and the upper edge of the seed panis cutterbar in the usual manner.

reinforced by a strip 16 which is secured'gto the seed pian and which projects just above the edge.

16,1924. Serial' No. 756,271.

A sifting screen 17 is mounted for shifting movement on the seed pan, the sifting screen having a bearing on the reinforcing or wearing strip 16. This sifting screen may be of any suitable construction and is shown for the salte of illustration `as consisting of a metal plate having openings which permit the passage of seed into the Aseed pan but which prevents the passage of hay thereinto. The forward edge of the sifting screen is wrapped around the central portion of an operating .rod 18 k,and is furtherv` secured .to this rod by` attaching bars 19 having por tions 2O rivetcdor otherwise securechajs at i0 the, Screen 17 and also .having Sleeve ,0r eyes' 22 .embracing and fixed.. t@ the operaties' met The Operating fied is loosely .mounted .in Slots 23 tor-11nd inv bearing brackets 24.# fixed to the cutter bar. The mounting ofthe rod --18 in the bearing brackets 211 is such that the rod may move aX .ially back and forth that is, transversely of the seed pan, or may move longitudinally of said seed panor may turn or move angularly.. 'lhe forward edge .of the screen 17 is notched, as at 25, to permit ythe rod and the screen to move transversely and longitudinal-ly ofthe seed pan orto be turnedto uncover `the seed pan. Y

At one end `the rod 18 is provided with a cranlrarm326 An operatingbar 27 is provided and has aliat vertical portion 28 connected to the pivot 12 which also serves to connect the pitman or operating element 18 with the cutter bar. This same operating bar 27 has its intermediate portion bent and twisted, as at 29, and has an upper hori 'zontal end portion 80 formed with an ini clined slot 31 in which the crank arm 26 is fitted.

With this arrangement when the cutter bar is being reciprocated the operating bar 30 is also moved back and forth. The back and forth movement of the operating bar causes the rod 18 and consequently the screen 17 to shift back and forth transversely of the seed pan and also to shift bach and forth longitudinally ofthe seed pan since the ends 31"L of the slot 31 alternatelyengage the crank arm 26 of the rod 18 to effect a back and forth transverse movement" and since the inclination of the slot causes the crank arm 26 and consequentlyrthe rod 18 to move and the screen 17 to shi-ft back and forth longitudinally of said panOf course, it iS to be understood that the Crank arm is i of the screen 17 into the seed pan 11i and the hay is moved baclf over the rear edge of the. screen and fallsV to the ground in the rear of the seed pan.v Although the operating bar 27 is held against horizontal swinging movement Vit maybe swung vertically about the pivot or bolt`12 to disengage it from the crank 'arm 26 when itis desired to Alift up the screen 17 to gain access to the interior ofthe seed pan.

From the foregoing it will be observed that the present invention provides anautomatic attachment for mowing machines which shakes the seed loose from the hay, which sifts the seed into the pan, which shakes or displacesthe hay olf the sifting Vscreenv and to the rear of the pan, which 'is adapted to fit any make of mower, which may he readily and easily attached and detached without drilling holes or otherwise modifying the construction of the mowing machine, which allows the cutter bar to be raised without lifting back the seed panv and which allows the operating bar 27 to be disrengaged from the crank arm 26 when the mower is notcutting.

I claim:

1. The combination with a cutter bar of a mowing machine and means for operating the bar ofa seed pan carriedby the cutter bar, a shifting screenoverlying the'seed pan, means for mounting the screen for shifting movement over the seed pan, and means operable from the means which operates the cutter bar for shifting said sifting screen.

2. The combination with a cutter bar of a vmowing' machine and means for operating the bar of a seed pan carried by the cutter bar, a sift-ing screen overlying the seed pan, means for mounting the screen for shifting movementtransversely and longitudinally over the seed pan, and means operable from the means which operates the cutter bar for shifting said sifting screen.

8. The combination with a cutter bar of a mowing machine and means for operating the bar of a seed pan carried by the cutter bar, a shifting screen overlying the seed pan, means for mounting the screen for shifting movement transversely and longitudinally over the seed pan and comprising a rod fixedlyT connected with the screen and bearings ,fixed to the cutter bar and having slots loosely receiving the rod, and means operable from the means which operates the cutter bar for shifting said sifting screen transversely and longitudinally over the pan.

4. The combination -with a cutter bar of aI mowing machine and means for operating the bar of a seed pan Ycarried by-t-he cutter bar, a shifting screen `overlying the seed pan, means for mounting the screen for shifting movement transversely and longitudinally over the seed pan and'comprising a rod fixedly connected with the screen and bearings fixed to the cutter bar and having slots loosely y'receivingthe rod, means operable from the means which operates the cutter bar for shifting said sift-ing screen transversely and longitudinally over the pan and including an operating bar connected with the means which operates the cutter bar, said operating bar having an inclined slot therein, said rod having an offset end received in said slot.
